What is the function of a Reservoir?

The primary function of a reservoir is to store water, particularly during periods of high flow, which can then be managed and used to meet water demand during drier times. Reservoirs play a crucial role in water resource management by helping to balance the supply of water with the varying demands from consumers, agriculture, and industry. By properly managing these water resources, reservoirs ensure a steady and reliable supply, which is essential for drinking water, irrigation, and other uses.

While reservoirs might provide recreational opportunities for communities, their primary goal is not recreational but rather to serve as a functional tool for water management. Heating water for consumption or treating wastewater are important processes in water systems, but they fall outside the specific function of a reservoir, which is concerned mainly with storage and management of raw water supplies.
